Split Rock Pleiospilos nelii
ABOUT
Pleiospilos nelii, commonly known as the Split Rock plant, has a distinctive and fascinating appearance. The plant consists of a pair or several pairs of thick, fleshy leaves that are tightly compacted together, almost resembling a cleft stone or a cloven hoof. These leaves are usually grey-green or brownish-green and may have a hint of purple or reddish tones. The texture of the leaves is somewhat rugged with a dotted pattern of small, darker speckles scattered across them. The Split Rock plant produces conspicuous flowers that emerge from the center of the leaf pair. These blooms are daisy-like in shape, large, and can be strikingly vibrant, often in shades of yellow or orange. The blooms open in the late afternoon and close by early evening and can be quite long-lasting. The overall look of this plant often intrigues observers due to its mimicry of stones or pebbles, which is a survival adaptation for blending into its natural rocky environments.

WaterThe Split Rock, or Pleiospilos nelii, requires minimal watering since it is a succulent plant adapting to arid conditions. During the growing season in spring and autumn, water once every 3 to 4 weeks, providing enough water to soak the soil, then allow it to dry out completely before watering again. This may equate to roughly 8-10 ounces depending on the size of the pot and soil mix. In winter, drastically reduce watering to once every other month as the plant goes dormant. Overwatering can be detrimental, leading to root rot, so it's crucial to err on the side of under-watering.
LightThe Split Rock plant thrives best in bright, indirect sunlight. An ideal location would be a south or west-facing windowsill where it can receive at least four to six hours of sunlight daily. However, it should be shielded from the intense midday sun to prevent sunburn on its leaves. Strong but filtered light will keep the plant healthy and encourage the vibrant colors to emerge in its foliage.
TemperatureSplit Rock prefers temperatures ranging from 50°F to 80°F, which makes it suitable for indoor environments. These plants can survive brief temperature extremes down to 40°F and up to 90°F but prolonged exposure outside this range can be harmful. The ideal temperature range is between 60°F and 70°F for optimal growth and flowering. Remember to protect your Split Rock from drafts and sudden temperature fluctuations.
PruningPruning the Split Rock plant is typically unnecessary as the plant naturally manages its old leaves, with new growth consuming the older, shriveled leaves. However, if dead or damaged leaves occur, they can be gently removed to tidy the plant and prevent potential rot. The best time for any necessary pruning is during the active growth period in spring or early autumn.
CleaningAs needed
SoilSplit Rock (Pleiospilos nelii) thrives in a well-draining soil mix consisting of 50% mineral grit such as coarse sand, perlite, or pumice mixed with 50% potting soil. It prefers a slightly acidic to neutral pH range of 6.0 to 7.5.
RepottingSplit Rock (Pleiospilos nelii) requires repotting infrequently, typically once every 2 to 4 years, as it prefers to be root-bound and grows slowly.
Humidity & MistingSplit Rock (Pleiospilos nelii) prefers low to moderate humidity levels and can tolerate dry air conditions typical of arid and semi-arid environments.
Suitable locationsIndoor
Place Split Rock near a sunny window and water sparingly.
Outdoor
Provide bright, filtered light and protect from extreme weather.

Life cycleCommonly known as "Split Rock," Pleiospilos nelii begins its life cycle as a seed, germinating in warm conditions with minimal water, mimicking its native arid environments. The seedling slowly matures, forming a pair of succulent leaves that are thick and fleshy, adapted to store water. As the plant grows, the old pair of leaves is reabsorbed to give way to a new pair, with the plant seldom having more than two pairs of leaves at a time. Split Rock flowers in the fall or early winter, producing bright, daisy-like flowers that open in the afternoon and close at night. After pollination, the plant sets seed within a fruit that dries and opens, releasing seeds for dispersal. Throughout its life, Pleiospilos nelii undergoes periods of dormancy, mainly in extreme hot or cold seasons, requiring little to no water during these times.
PropogationPropogation time
Spring to Summer
The best time to propagate a Split Rock plant, or Pleiospilos nelii, is during the warmer months when the plant is not in its dormant winter phase. The most popular method of propagation for Split Rock is through seeds. The process involves sowing the seeds in a well-draining cactus mix, barely covering them with the substrate. Place the container in a warm area with bright, indirect sunlight and maintain a consistent temperature of about 70°F (21°C). Water sparingly, just enough to keep the substrate slightly moist until germination occurs, which typically is within a few weeks. Once the seedlings are large enough to handle, they can be transplanted into individual pots. Care should be taken not to over-water, as the young plants are susceptible to rot.
